Overview
Misalignment of the visual axes, constant or intermittent, that parents commonly notice as an eye that turns, whether inward, outward, upward or downward. Cover testing or corneal reflex assessment shows a manifest deviation, and reduced stereopsis, suppression, amblyopia or significant refractive error frequently coexist. An acute or new-onset deviation is a different clinical problem from a longstanding childhood turn and warrants prompt assessment.
Recognition
Symptoms: what patients report
- Parents notice one eye turning in, out, up, or down.
- Eye turn may be intermittent or constant.
- Child may have reading avoidance, poor attention to near work, or reduced depth awareness.
Signs: what the examination shows
- Manifest deviation on cover testing or corneal reflex assessment.
- Reduced stereopsis or suppression may be present.
- Amblyopia or refractive error may coexist.
- Subtype clues may include near hyperopic esotropia, distance/fatigue-related exotropia, apparent crossing with normal Hirschberg and cover test, or ocular motility restriction with head posture.
- A stable long-standing pattern is clinically different from sudden-onset deviation.
